Have you ever judged your date for their credit card?

I've been out with this guy a few times and for the first dates he insisted on paying, but last night I said I thought it was about time we split it. Now, he's got a great job, and as such has one of those top-of-the-range credit cards that offers amazing travel benefits and such. While I really like what I do, I don't make anywhere near as much as he does, and though I have good credit, I still have just the one Discover card I've had since college. This is what I put my share of the tab on last night... So I'm curious: Have you ever judged your date based on the credit card they use? I just don't want this guy making false assumptions about my financial situation or my ambition...
